xAI has officially launched its latest flagship AI model Grok4, marking another major breakthrough in the field of artificial intelligence. According to official information, Grok4 was globally released through a live stream event by the xAI official account on July 9th at 8 PM Pacific Time, drawing widespread attention from the industry and users. AIbase has compiled the latest information and provides an in-depth analysis of the highlights and impact of Grok4.
Grok4: Performance Upgraded Across the Board, Challenging Top AI Models
Grok4 is the new generation AI model introduced by xAI following Grok3, aiming to directly compete with leading models such as OpenAI's GPT-4o and Google's Gemini 3.0. According to xAI, Grok4 performs exceptionally well in core benchmark tests such as mathematics, logical reasoning, and code generation, with some metrics surpassing existing top models. For example, in the AIME’25 mathematical reasoning test and the GPQA scientific question benchmark, Grok4 shows significant advantages, with a notable improvement in logical reasoning capabilities compared to Grok3.
Additionally, Grok4 has a context window of 131,072 tokens, slightly higher than Grok3's 128,000 tokens, supporting more complex long-text processing. This makes Grok4 more efficient in handling multi-domain complex tasks, suitable for a wide range of scenarios from academic research to daily writing.
Two-Model Strategy: Grok4 and Grok4 Code Go Hand in Hand
xAI has launched two versions of Grok4 to meet different user needs: the general model Grok4 and the Grok4 Code, specifically designed for developers. The general model is aimed at everyday users, supporting AI tasks such as writing, research, and translation, emphasizing logical reasoning and multimodal processing capabilities. Grok4 Code integrates professional programming tools, similar to Cursor's code generation and debugging features, providing developers with code generation, error detection, and contextual development support. xAI stated that the launch of Grok4 Code aims to meet the growing demand for automated programming assistant services.
Notably, Grok4 currently only supports the text modality, and functions such as visual processing and image generation are expected to be added in future updates. This phased release strategy demonstrates xAI's cautious approach to ensuring model stability and functional completeness.
Real-Time Data and Controversy Coexist: Grok4's Unique Positioning
Grok4 continues xAI's usual "real-time data" advantage, integrating real-time data from the X platform (formerly Twitter) deeply, providing users with responses based on the latest developments. This gives it a clear advantage when dealing with news, trends, and hot topics. However, this feature has also sparked controversy. Previously, Grok faced inaccurate responses on sensitive topics such as the Israel-Iran conflict, which led to discussions about its information reliability. xAI states that Grok4 has significantly improved fact-checking capabilities through optimized training data and algorithms, but still recommends users to independently verify critical information.
Additionally, Grok4 is positioned as an AI that "maximizes the pursuit of truth," attempting to provide more direct answers on controversial topics without traditional filtering. This characteristic has caused polarized reactions among users, with some appreciating its openness, while others are concerned about potential bias risks.
Live Stream Highlights and Future Prospects
The release live stream on July 9th attracted the attention of AI enthusiasts around the world. The xAI team demonstrated Grok4's powerful capabilities in solving complex mathematical problems, code debugging, and real-time data analysis during the live stream. The broadcast also revealed that xAI plans to further expand Grok4's multimodal capabilities, including image generation and video processing, to meet broader application scenarios.
The rapid development of xAI relies on its strong computing resources. Grok4's training is supported by xAI's Colossus supercomputer, with approximately 200,000 GPUs, ten times the training scale of Grok3. This not only reflects xAI's solid strength in AI infrastructure but also lays the foundation for future iterations.
AIbase believes that the release of Grok4 is not only a demonstration of xAI's technical capabilities, but also marks a new stage in the competition within the AI industry. By focusing on reasoning capabilities, real-time data integration, and developer tools, Grok4 showcases xAI's balanced strategy between general AI and specialized applications. However, its "no-filter" positioning may face challenges in terms of information accuracy and ethics. In the future, xAI needs to further optimize content review mechanisms while improving model performance to gain broader user trust.
Grok4 is now available to selected developers via xAI's API, and regular users can experience its features through the Premium+ subscription on the X platform or Grok.com.
